Hello,
this is a little bit hard to tell from the outside. So for the moment I have
only some general ideas:
Did the algorithm converge in both cases? If not, I would have less confidence
in the results.
One thing to consider besides the effect size and direction is the variability
of the est
Dear Kersten,
Thanks for reply. I have new question.
When I set model use total_i_vol_stats = lme_fit_FS(X,[1 2],Y(:,2),ni)
and total_i_vol_stats = lme_fit_FS(X,[1],Y(:,2),ni).
But Bhat of two models' year have a lot different, for example, with 2 is
1.2422 without 2 is -0.5737. The direction has
Hi
sorry for the delayed response, I was not able to reply during the last
week.
You are right that the F-test provided in the LME toolbox initially
does not provide information about the direction of the effects.
You could do the following:
First, it is always useful to plot the data to get a
Dear Kersten,
I have a question about LME model. After I acquired p value, could I know
which group is bigger?
Thanks,

Dear Kersten,
Thanks a lot, it's really help. I have another question, after I got
results that two group have significant, then how could I get direction?
Thanks,

If I understood correctly,
Dear Kersten,
Thanks, I find it. And I have other questions:
1. The intercepts all set as one, so in this model it doesn't separate
different subjects, or can say no individual subject change rate?
2. Should we set age according to different timepoint, or just use baseline
age?
Thanks,

Hello Lanbo,
the univariate example data can actually be downloaded from the LME
tutorial website:
Search for: "An optional sample dataset which can be used to become
familiar with the LME Matlab tools can be found here". The linked
tar.gz archive contains two folders, one for the univariate and
Dear Experts,
Hi,
There is no example detail on website of LME tutorial. I have some question
about it.
Could you send me the table of ADNI univariate example data?
Thanks,
Lanbo
